Ap Dijksterhuis, a psychologist at Radboud University in the Netherlands (and expert on unconscious thought), has done some studies that look at how people shop for homes, and how they often fall victim to what he calls a "weighting mistake".

Consider two housing options: a three bedroom apartment that is located in the middle of a city, with a ten minute commute time, or a five bedroom McMansion in the suburbs, with a forty-five minute commute. "People will think about this trade-off for a long time," Dijksterhuis writes. "And most them will eventually choose the large house. After all, a third bathroom or extra bedroom is very important for when grandma and grandpa come over for Christmas, whereas driving two hours each day is really not that bad." What's interesting is that the more time people spend deliberating, the more important that extra space becomes.
